Based on the MinGW header. [FREELDR] Refactor and optimize the IDE driver. Fix long-standing bugs, which have a negative impact on the boot stability. - Make the driver more ATA specification compliant. - Improve the speed of device detection. - Remove inconsistent delays. - Support modern hard drives with sector size greater than 512 bytes. - Add basic error recovery. - Move private definitions to a separate private header. - Remove the useless AtaFree API method. --- boot/freeldr/freeldr/arch/drivers/hwide.c | 1749 +++++++++++++-------- boot/freeldr/freeldr/arch/drivers/hwidep.h | 387 +++++ boot/freeldr/freeldr/arch/i386/pc98/machpc98.c | 1 - boot/freeldr/freeldr/arch/i386/pc98/pc98disk.c | 9 +- boot/freeldr/freeldr/arch/i386/xbox/machxbox.c | 1 - boot/freeldr/freeldr/arch/i386/xbox/xboxdisk.c | 51 +- boot/freeldr/freeldr/include/arch/i386/machpc98.h | 1 - boot/freeldr/freeldr/include/arch/i386/machxbox.h | 1 - boot/freeldr/freeldr/include/hwide.h | 341 +--- sdk/include/ddk/ata.h | 558 ++++++- 10 files changed, 2002 insertions(+), 1097 deletions(-) diff --git a/boot/freeldr/freeldr/arch/drivers/hwide.c b/boot/freeldr/freeldr/arch/drivers/hwide.c index 9eb92ada048..2baffe48345 100644 --- a/boot/freeldr/freeldr/arch/drivers/hwide.c +++ b/boot/freeldr/freeldr/arch/drivers/hwide.c @@ -1,371 +1,750 @@ /* * PROJECT: FreeLoader - * LICENSE: GPL-2.0-or-later (https://spdx.org/licenses/GPL-2.0-or-later) + * LICENSE: MIT (https://spdx.org/licenses/MIT) * PURPOSE: ATA/ATAPI programmed I/O driver. - * COPYRIGHT: Copyright 2019-2020 Dmitry Borisov (di.sean(a)protonmail.com) + * COPYRIGHT: Copyright 2019-2025 Dmitry Borisov (di.sean(a)protonmail.com) */ /* INCLUDES *******************************************************************/ #include <freeldr.h> -#include <hwide.h> /* DDK */ #include <ata.h> #include <scsi.h> +#include <hwide.h> +#include "hwidep.h" + #include <debug.h> DBG_DEFAULT_CHANNEL(DISK);

Introduce a 3rd-stage bootsector for complex code. CORE-14235 - Why was the previous bootsector broken? Because of hardcoded inode size, hardcoded freeldr base address, etc. - Why is there a extldr.sys? The extldr.sys was introduced because the limited code space in the bootsector prevents adding new features, such as Ext4 full extents support. - What is extldr.sys and What does it do? It is the helper file for the Ext bootsector and that is necessary for adding Ext4 support. It locates the freeldr.sys file, loads it into memory and runs it. --- boot/freeldr/bootsect/CMakeLists.txt | 6 +- boot/freeldr/bootsect/ext.S | 726 +++++++++++++++++++++++++++++++++++ boot/freeldr/bootsect/ext2.S | 688 --------------------------------- boot/freeldr/bootsect/extldr.S | 583 ++++++++++++++++++++++++++++ 4 files changed, 1313 insertions(+), 690 deletions(-) diff --git a/boot/freeldr/bootsect/CMakeLists.txt b/boot/freeldr/bootsect/CMakeLists.txt index a46c9066c6a..986d399d13e 100644 --- a/boot/freeldr/bootsect/CMakeLists.txt +++ b/boot/freeldr/bootsect/CMakeLists.txt @@ -4,7 +4,8 @@ include_directories(${REACTOS_SOURCE_DIR}/boot/freeldr) if(ARCH STREQUAL "i386" OR ARCH STREQUAL "amd64") CreateBootSectorTarget(dosmbr ${CMAKE_CURRENT_SOURCE_DIR}/dosmbr.S ${CMAKE_CURRENT_BINARY_DIR}/dosmbr.bin 7c00) -
